Update: I was unfortunately not aware of Shamus Young's severe criticism of Fallout 3 available here to link in the original piece and I regret that. It dovetails rather nicely with what I've written and it's much better executed than my piece. I strongly recommend anyone...

iSlack

We all slack a little, some more than others. Now you can slack a little (with the free version) or a lot (with the paid version) while playing iSlack, on your iPhone, iPod Touch or iPad. It’s a balance alright, some where between keeping your job and keeping your happiness. You will need to pay close attention to your surroundings to maximize your happiness and score, but look out for the boss. It only takes one slip up and you’re out of here.
